Phil K 1 Posted November 12, 2020 Just had a customer come in to ask for my help on a Yaris I sold her a few years back. She’s elderly so I’d rather try and help her than her getting ripped off. It’s a 55 Yaris 1:3 last of the older shape. Only done 65k but sounds like a bag of nails rattling. Regular oil and filter changes and drives spot on with plenty of poke and no mis fire. It isn’t using any oil or water and it’s as clean as a whistle under the hood. My thought is timing chain but surely if it had stretched it will cause a misfire and bad running as the timing would be out. I will change oil filter and put quality oil in tomorrow but in the worse case scenario would it be cost effective to have a new chain? Thanks in advance for any advise.

Halfpenny 114 Posted November 12, 2020 These don't generally suffer with timing chains. Check the exhaust manifold heat shield to see if its loose. Has it just had oil & filter recently? - some poor quality filters around... Other than that its use a stethscope and remove belts to isolate rotating parts.

Frank Cannon 812 Posted November 12, 2020 Dip the clutch.....if it stops rattling will be gearbox....assuming you've checked the easy stuff hence the request for help. While not common, I've had two Yaris over the years with u/s boxes and both sounded like an old Mini A Series with bad drop gears. 1 Share this post Link to post Share on other sites

These grow old gracefully - just get sluggish engagement and slipping when worn out. Don't ever remember having one with a hard mechanical failure. I've stripped and resealed a few.. Old-school Aisin boxes never die. Share this post Link to post Share on other sites
